Definitions

  • the present model concerns a tool used in the mounting operation of a tyre onto a rim.
  • said tool comprising a body equipped with a base (or fixed jaw) and with a mobile jaw to which means are operatively connected suitable for bringing said mobile jaw closer to said fixed jaw to jam the edge of the rim between them so as to lock said body to the edge of the rim.
  • the lower surface of the base when the tool is fixed to the edge of the rim, presses against the sidewall of the tyre so as to keep the bead of the tyre distanced from the edge of the rim and allow it to slide in the radial direction, during the rotation of the wheel, inside the central channel of the rim.
  • the surface of the tool is shaped in such a way as to promote the sliding thereof.
  • these tyres have, on the sidewall, a raised band intended to rest on the edge of the rim, said band interfering with the surface of the tool blocking the sliding in the radial direction of the sidewall of the tyre.
  • the purpose of the present finding is to overcome the drawbacks of the prior art in a simple and rational way.
  • a tool for mounting a tyre on a rim suitable for making it easier to insert the bead of the tyre inside the bead-stopping edge of the rim, comprising a body equipped with a fixed jaw and a mobile jaw to which means are operatively connected suitable for bringing said mobile jaw closer to said fixed jaw to lock said body to the edge of the rim, a base intended to be rested against the sidewall of the tyre is associated with said body, said base being fixedly connected to said body so as to be able to oscillate in the direction of the axis of the rim following the movement of the bead to promote the insertion thereof inside the bead-stopping edge to take it near to the channel of the rim.
  • the base can oscillate with respect to the jaws that lock the tool on the rim, during the mounting of the tyre, it is avoided that the carcass thereof be subjected to excessive and undesired tensions.
  • the base of the tool oscillates in the direction of the axis of the rim making it easier for the bead to slide towards the channel of the rim and avoiding the occurrence of undesired tensions in the carcass of the tyre.
  • Fig. 1 shows a schematised perspective view of the device according to the finding during the mounting of the tyre onto the rim.
  • Fig. 2 illustrates a side view of the finding.
  • Fig. 3 illustrates the section III-III of Fig. 2.
  • Fig. 4 illustrates the section IV-IV of Fig. 3.
  • Fig. 5 illustrates a front view of the finding.
  • Fig. 6 illustrates a partially sectioned plan view of the finding.
  • the rim 1 is supported and locked by a normal device 3, of a tyre-dismounting machine that is not illustrated.
  • the suitable tool 4 Fixed onto the bead-stopping edge 100 of the rim 1 is the suitable tool 4 that has the function of making the insertion of the bead 200 of the tyre 2 inside the bead-stopping edge 100 of the rim 1 easier by directing it towards the channel of the rim itself.
  • the tool 4 (Figs. 2, 3 and 4) comprises an outer body 5 consisting of two identical plates 6 joined together by a shaped element 7. Below each plate 6 a tooth 8 is provided, fixed canti-levered and projecting in front of the plates 6 themselves. The two teeth 8 make a fixed jaw with which the tool 4 is provided.
  • a second body 9 is received the front portion of which sticks out from the two plates 6 and defines a mobile jaw 10 suitable for being brought towards and/or away from the two teeth 8 that constitute the fixed jaw.
  • Said second body 9 is fixedly connected to the plates 6 thanks to a pin 11 so as to be able to rotate with respect to the plates.
  • the body 9 has a fork 90 that receives a second pin 12, which has a threaded central hole 120 with which the actuation means 13 are associated that allow the rotation of the body 9 with respect to the outer body 5.
  • Said actuation means 13 comprise a screw 130 that is slotted into a hole 70, of the element 7 that joins the two plates 6, and the upper free end of which carries a manoeuvring handle 131.
  • the lower end of the screw 130 is threaded and screwed into the matching threaded hole 120 of the pin 12.
  • the body 9 also has a recess 91 that is open on top and that receives a spring 15 that is compressed between the bottom of the recess 91 and the lower surface of the element 7.
  • the function of the spring 15 is to keep the threads of the hole 120 of the pin 12 always in contact against the threads of the screw 130. Said spring 15 is always kept in the correct position by a grain 16 screwed into a threaded hole of the element 7 and the lower end of which is slotted between the spirals of the spring 15 itself.
  • the body 9 has, at the pin 11, a through opening 92 in which a shaft 17 is received.
  • the shaft 17 has a cylindrical upper portion 170 that is slotted onto the pin 11 with the interposition of a cage of rollers 18.
  • the shaft 17 has, on the other hand, a threaded portion 171 onto which a base 19 is screwed.
  • the base 19 comprises a discoidal lower portion 190 arranged below the plates 6 and a threaded upper band 191 that is screwed onto the shaft 17.
  • the base 19 is screwed onto the shaft 17 it is possible to adjust its position and therefore the intensity of the force with which the discoidal portion 190 of the base 19 acts on the sidewall of the tyre 2. For this purpose indeed it is sufficient to unscrew or screw the base 19 onto the shaft 17.
  • the shaft 17 can oscillate between two extreme positions delimited by two limit switch pins 20 and 21.
  • the shaft 17 is kept rested against the pin 20 thanks to the action of a traction spring 22 one end of which is fixedly connected to the element 7 and the other end of which is restrained by the shaft 17 through a split pin 23 (Fig. 4).
  • the rim 1 is made to rotate by actuating the tyre-dismounting machine and simultaneously the tool that takes care of pressing on the sidewall of the tyre 2.
  • the base 19 oscillates towards the axis of the rim from the initial rest position, in which the shaft 17 rest on the pin 20, to the advanced position in which the shaft 17 rests on the pin 21.
  • This oscillation which is gradual during the rotation of the rim, makes the bead of the tyre 2 easier to direct in the direction of the bead-stopping edge 100 of the rim 1 allowing it to be inserted below the edge 100 itself and inside the channel of the rim.
